Question

Which two points have an undefined slope

Answer 1

C. (-3, -3) and (-3, 3)

Explanation:

(-1, 1) and (1, -1)

Slope = (-1-1) / (1 - (-1))

= -2 / 2 = -1.

(-1,2) and (2,2)

Slope = ( 2-2)/ ( 2 - -2)

= 0

(-3, -3) and (-3, 3)

Slope = (3 - -3) / (-3 - (-3)

= 6 / (-3+3)

= 6/0 - UNDEFINED.

The line joining these points is vertical.

Answer 2
